Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor structure technology, and in particular to a sampling device for a high-pressure reactor. Background Technology
[0002] Sampling of chemical reagents is an essential process in chemical experiments or research. Currently, in chemical production processes, sampling of reaction liquids in pressurized reactors is mainly achieved through the following two methods:
[0003] One method involves welding a pipe directly to the reactor and installing a valve at the other end. During sampling, the valve is opened, and the sample is released using the pressure inside the reactor. While simple, this method is extremely dangerous. If the pressure inside the reactor is high or if the contents contain flammable materials that come into contact with air, the sample flow rate can be too fast and uncontrollable. This could lead to the sample igniting upon contact with air, posing a safety hazard to the personnel. Another method involves connecting a valve to the outside of the pipe, followed by a storage container. The valve is closed after the sample flows into the container. However, this method merely adds a backflow space, and similar safety risks exist when sampling from a high-pressure hydrogenation reactor.
[0004] Existing methods also cannot achieve stratified sampling of high-altitude reactors, and the sampling results are not representative. Utility Model Content
[0005] The purpose of this invention is to provide a sampling device for a high-pressure reactor, which can achieve multi-layer sampling of reactants inside the high-pressure reactor. At the same time, the sampling column can be electrically raised and lowered by a movable motor, making sampling more convenient.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A sampling device for a high-pressure reactor is characterized by comprising a reactor body, a baffle, a sampling column, and a movable motor.

[0010] Preferably, the bottom of the stirring shaft is rotatably connected to the vessel body via a base bearing, and a packing seal is provided between the top of the stirring shaft and the vessel body.
[0011] Preferably, the baffle is arc-shaped, the thickness at both ends of the baffle is less than the thickness in the middle, and a gap is provided between the baffle and the stirring blade.
[0012] Preferably, one side of the baffle is provided with multiple sets of limiting ring seats from top to bottom in the sampling channel, and the sampling column is interspersed in the multiple sets of limiting ring seats.
[0013] Preferably, the sampling column has two sets of limiting grooves symmetrically opened at both ends, and the limiting ring seat has a limiting protrusion in the corresponding limiting groove.

An observation mirror is provided on the slot, and the observation mirror is sealed and installed on the outside of the slot by a cover plate.
